Its from a big floor model, with transistors and even a view ICs, I scrapped it, too bad it was smashed, its pretty hard to find old electronics where I live.
I checked the winding on Ohms an found 4 sets and even separated out the 2'ndry in order.
With 120V in on a solid black pair of wires, , on the main secondary set I get
0V
145V
220
248
253
274
350
or 0V,76,97,102,130,205
Then there's a winding with 115V on it, its resistance was about 0.34Ohm. It has 2 grey wires. The Blk pair had 5.6O and I put mains 120V on on its winding.
Does the black sound more like Primary ?
Then on a separate sec.wind. there's 5.5V , I assume the CRT heater winding
There was another little transformer in this TV, 120V to 5.7V. so I assume thats run of that gray pair of 115V ? and is an audio transformer I guess.
I don't have the schematic tho, but that sounds like the gray winding is only for small power for audio output, and not suitable above say 5-10W ? IDK
So for now I could use 102V (or well what ever combo) and try to power up a small vacuum tube radio
So this thing with some variac and switches and light blub limiter should work great
